The actors in this film is a-list and give great performances. John Cusack is a worthy main character and is fantastic as a former cop who tries to put the pieces together while finding out that he is the main one.

The directing and editing of this film are great, and without giving too much away, the editing takes a crucial role halfway through the film.

Being a murder thriller, there is a fair amount of violence and gore but everything moves the story along.

By the end of the movie, while not absurd, definitely not a documented occurrence.
